I recently purchased the c180 kompressor 2003 auto after it being sat on a drive for 12month+. There has been a number of issues resulting in me fitting new battery and new alternator. Problem solved.

Now there seems to be a judder when idling. When its driving it seems fine but sometimes stalls, especially when steering on full lock. Also when in reverse sometimes the revs go up and down.

The warning on the dash "coolant visit workshop" shows up after 3-4 seconds of the engine being turned on.

A friend plugged the car into the bosch diagnostic system and did a full scan. There was numerous faults that it showed.

I have replaced the brass temperature sensor to the left hand side of the engine at the top and also the spark plugs.
I was told to replace the coil pack on number 1cylinder but unsure which is number 1.

Just had car out on road with M.A.F. sensor unplugged, no stalling, no juddering and smooth idle. would this therefore be the maf (air sensor) be the issue?

Any help would be much appreciated.. Thanks in advance.
